1. update - modify existent only. To avoid side effect of indexer use:

   int val;
   if (dic.TryGetValue(key, out val))
   {
       // key exist
       dic[key] = val;
   }
   

2. update or (add new if value doesn't exist in dic)

   dic[key] = val;
   

   for instance:

   d["Two"] = 2; // adds to dictionary because "two" not already present
   d["Two"] = 22; // updates dictionary because "two" is now present
   

Try this

 <div id="app">
  <p>
    <label for='terms'>
      <input id='terms' type='checkbox' v-model='terms' /> Click me to enable
    </label>
  </p>
  <input :disabled='isDisabled'></input>
</div>

vue js

new Vue({
  el: '#app',
  data: {
    terms: false
  },
  computed: {
    isDisabled: function(){
        return !this.terms;
    }
  }
})

Specifically for SQL-SERVER you can achieve that in many different ways.For given real example we took Customer table here.

Example 1: With "SET ROWCOUNT"

SET ROWCOUNT 10
SELECT CustomerID, CompanyName from Customers
ORDER BY CompanyName

To return all rows, set ROWCOUNT to 0

SET ROWCOUNT 0  
SELECT CustomerID, CompanyName from Customers
    ORDER BY CompanyName

Example 2: With "ROW_NUMBER and OVER"

With Cust AS
( SELECT CustomerID, CompanyName,
ROW_NUMBER() OVER (order by CompanyName) as RowNumber 
FROM Customers )
select *
from Cust
Where RowNumber Between 0 and 10

Example 3 : With "OFFSET and FETCH", But with this "ORDER BY" is mandatory

SELECT CustomerID, CompanyName FROM Customers
ORDER BY CompanyName
OFFSET 0 ROWS
FETCH NEXT 10 ROWS ONLY

Hope this helps you.

It depends.

Start with Basic I/O, take a look at Properties, take a look at Preferences API and maybe even Java API for XML Processing and Java Architecture for XML Binding

And if none of those meet your particular needs, you could even look at using some kind of Database

You can use Decode as well:

SELECT DISTINCT a.item, decode(b.salesman,'VIKKIE','ICKY',Else),NVL(a.manufacturer,'Not Set')Manufacturer
FROM inv_items a, arv_sales b
WHERE a.co = b.co
      AND A.ITEM_KEY = b.item_key
      AND a.co = '100'
AND a.item LIKE 'BX%'
AND b.salesman in ('01','15')
AND trans_date BETWEEN to_date('010113','mmddrr')
                         and to_date('011713','mmddrr')
GROUP BY a.item, b.salesman, a.manufacturer
ORDER BY a.item

You can overcome this error in two simple ways

First way

using namespace std;
include <string>
// then you can use string class the normal way

Second way

// after including the class string in your cpp file as follows
include <string>
/*Now when you are using a string class you have to put **std::** before you write 
string as follows*/
std::string name; // a string declaration

worked for me too:

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    Date parsed = null;
    try {
        parsed = sdf.parse("02/01/2014");
    } catch (ParseException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    java.sql.Date data = new java.sql.Date(parsed.getTime());
    contato.setDataNascimento( data);

    // Contato DataNascimento era Calendar
    //contato.setDataNascimento(Calendar.getInstance());         

    // grave nessa conexão!!! 
    ContatoDao dao = new ContatoDao("mysql");           

    // método elegante 
    dao.adiciona(contato); 
    System.out.println("Banco: ["+dao.getNome()+"] Gravado! Data: "+contato.getDataNascimento());

basically 32bit architecture can address 4GB as you expected. There are some techniques which allows processor to address more data like AWE or PAE.

SharpSSH should do the job. http://www.codeproject.com/Articles/11966/sharpSsh-A-Secure-Shell-SSH-library-for-NET

You should use the = operator for string comparison:

Sourcesystem="ABC"

if [ "$Sourcesystem" = "XYZ" ]; then 
    echo "Sourcesystem Matched" 
else
    echo "Sourcesystem is NOT Matched $Sourcesystem"  
fi;

man test says that you use -z to match for empty strings.

Youtube doesn't provide any option for an end time, but there alternative sites that provide this, like Tubechop. Otherwise try writing a function that either pauses video/skips to next when your when your video has played its desired duration.

OR: using the Youtube Javascript player API, you could do something like this:

function onPlayerStateChange(evt) {
    if (evt.data == YT.PlayerState.PLAYING && !done) {
        setTimeout(stopVideo, 6000);
        done = true;
    }
}

Send your file as a base64 string.

 var element = angular.element('<a/>');
                         element.attr({
                             href: 'data:attachment/csv;charset=utf-8,' + encodeURI(atob(response.payload)),
                             target: '_blank',
                             download: fname
                         })[0].click();

If attr method not working in Firefox You can also use javaScript setAttribute method

If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide(), with additional arguments, as follows:

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this).hide('slide',{direction:'right'},1000);

            });
    });

JS Fiddle demo.

Without using jQuery UI, you could achieve your aim just using animate():

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this)
                    .animate(
                        {
                            'margin-left':'1000px'
                            // to move it towards the right and, probably, off-screen.
                        },1000,
                        function(){
                            $(this).slideUp('fast');
                            // once it's finished moving to the right, just 
                            // removes the the element from the display, you could use
                            // `remove()` instead, or whatever.
                        }
                        );

            });
    });

If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js

The ID you are trying is an serverside.

That is going to render in the browser differently.

try to get the ID by watching the html in the Browser.

var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;

this may works.

Or do that ClientID method. That also works but ultimately the browser will get the same thing what i had written.

Sorting the array is unnecessary and inefficient. There's a variation of the QuickSort (QuickSelect) algorithm which has an average run time of O(n); if you sort first, you're down to O(n log n). It actually finds the nth smallest item in a list; for a median, you just use n = half the list length. Let's call it quickNth (list, n).

The concept is that to find the nth smallest, choose a 'pivot' value. (Exactly how you choose it isn't critical; if you know the data will be thoroughly random, you can take the first item on the list.)

Split the original list into three smaller lists:

• One with values smaller than the pivot.
• One with values equal to the pivot.
• And one with values greater than the pivot.

You then have three cases:

1. The "smaller" list has >= n items. In that case, you know that the nth smallest is in that list. Return quickNth(smaller, n).
2. The smaller list has < n items, but the sum of the lengths of the smaller and equal lists have >= n items. In this case, the nth is equal to any item in the "equal" list; you're done.
3. n is greater than the sum of the lengths of the smaller and equal lists. In that case, you can essentially skip over those two, and adjust n accordingly. Return quickNth(greater, n - length(smaller) - length(equal)).

Done.

If you're not sure that the data is thoroughly random, you need to be more sophisticated about choosing the pivot. Taking the median of the first value in the list, the last value in the list, and the one midway between the two works pretty well.

If you're very unlucky with your choice of pivots, and you always choose the smallest or highest value as your pivot, this takes O(n^2) time; that's bad. But, it's also very unlikely if you choose your pivot with a decent algorithm.

Sample code:

import java.util.*;

public class Utility {
   /****************
   * @param coll an ArrayList of Comparable objects
   * @return the median of coll
   *****************/
   
   public static <T extends Number> double median(ArrayList<T> coll, Comparator<T> comp) {
      double result;
      int n = coll.size()/2;
      
      if (coll.size() % 2 == 0)  // even number of items; find the middle two and average them
         result = (nth(coll, n-1, comp).doubleValue() + nth(coll, n, comp).doubleValue()) / 2.0;
      else                      // odd number of items; return the one in the middle
         result = nth(coll, n, comp).doubleValue();
         
      return result;
   } // median(coll)
   
   

   /*****************
   * @param coll a collection of Comparable objects
   * @param n  the position of the desired object, using the ordering defined on the list elements
   * @return the nth smallest object
   *******************/
   
   public static <T> T nth(ArrayList<T> coll, int n, Comparator<T> comp) {
      T result, pivot;
      ArrayList<T> underPivot = new ArrayList<>(), overPivot = new ArrayList<>(), equalPivot = new ArrayList<>();
      
      // choosing a pivot is a whole topic in itself.
      // this implementation uses the simple strategy of grabbing something from the middle of the ArrayList.
      
      pivot = coll.get(n/2);
      
      // split coll into 3 lists based on comparison with the pivot
      
      for (T obj : coll) {
         int order = comp.compare(obj, pivot);
         
         if (order < 0)        // obj < pivot
            underPivot.add(obj);
         else if (order > 0)   // obj > pivot
            overPivot.add(obj);
         else                  // obj = pivot
            equalPivot.add(obj);

      // recurse on the appropriate list
      
      if (n < underPivot.size())
         result = nth(underPivot, n, comp);
      else if (n < underPivot.size() + equalPivot.size()) // equal to pivot; just return it
         result = pivot;
      else  // everything in underPivot and equalPivot is too small.  Adjust n accordingly in the recursion.
         result = nth(overPivot, n - underPivot.size() - equalPivot.size(), comp);
         
      return result;

To remove all the constraints from the DB:

SELECT 'ALTER TABLE ' + Table_Name  +' DROP CONSTRAINT ' + Constraint_Name
FROM Information_Schema.CONSTRAINT_TABLE_USAGE

This works for me, I only need first numbers in string:

TO_NUMBER(regexp_substr(h.HIST_OBSE, '\.*[[:digit:]]+\.*[[:digit:]]*'))

the field had the following string: "(43 Paginas) REGLAS DE PARTICIPACION".

result field: 43

You should use font-size for controlling the height, it is widely supported amongst browsers. And in order to add spacing, you should use padding. Forexample,

.inputField{
  font-size: 30px;
  padding-top: 10px;
  padding-bottom: 10px;
}

def get_line_number(phrase, file_name):
    with open(file_name) as f:
        for i, line in enumerate(f, 1):
            if phrase in line:
                return i

You can now do this in most "modern" browsers!

Here is the original article I read (posted July 10, 2010): HTML5: Changing the browser-URL without refreshing page.

For a more in-depth look into pushState/replaceState/popstate (aka the HTML5 History API) see the MDN docs.

TL;DR, you can do this:

window.history.pushState("object or string", "Title", "/new-url");

See my answer to Modify the URL without reloading the page for a basic how-to.

I'm using this function to format US numbers.

function formatUsPhone(phone) {

    var phoneTest = new RegExp(/^((\+1)|1)? ?\(?(\d{3})\)?[ .-]?(\d{3})[ .-]?(\d{4})( ?(ext\.? ?|x)(\d*))?$/);

    phone = phone.trim();
    var results = phoneTest.exec(phone);
    if (results !== null && results.length > 8) {

        return "(" + results[3] + ") " + results[4] + "-" + results[5] + (typeof results[8] !== "undefined" ? " x" + results[8] : "");

    }
    else {
         return phone;
    }
}

It accepts almost all imaginable ways of writing a US phone number. The result is formatted to a standard form of (987) 654-3210 x123

The ENABLEDELAYEDEXPANSION part is REQUIRED in certain programs that use delayed expansion, that is, that takes the value of variables that were modified inside IF or FOR commands by enclosing their names in exclamation-marks.

If you enable this expansion in a script that does not require it, the script behaves different only if it contains names enclosed in exclamation-marks !LIKE! !THESE!. Usually the name is just erased, but if a variable with the same name exist by chance, then the result is unpredictable and depends on the value of such variable and the place where it appears.

The SETLOCAL part is REQUIRED in just a few specialized (recursive) programs, but is commonly used when you want to be sure to not modify any existent variable with the same name by chance or if you want to automatically delete all the variables used in your program. However, because there is not a separate command to enable the delayed expansion, programs that require this must also include the SETLOCAL part.

This works in Firefox 3, Internet Explorer 8, Internet Explorer 8 compatibility mode, Opera, and Safari.

Here is a functional way to remove nulls from an Object using ES6 without mutating the object using only reduce:

const stripNulls = (obj) => {
  return Object.keys(obj).reduce((acc, current) => {
    if (obj[current] !== null) {
      return { ...acc, [current]: obj[current] }
    }
    return acc
  }, {})
}

It's now builtin in MySQL 8.0 and MariaDB 10.2:

SELECT
  itemID, COUNT(*) as ordercount,
  ROW_NUMBER OVER (PARTITION BY itemID ORDER BY rank DESC) as rank
FROM orders
GROUP BY itemID ORDER BY rank DESC

Another solution :

create the SSH keys, type ssh-keygen -t rsa -C "[email protected]". This will create both id_rsa and id_rsa.pub files.

Add the id_rsa to ssh list on local computer: ssh-add ~/.ssh/id_rsa.

After generating the keys get the pubkey using :

cat ~/.ssh/id_rsa.pub 

you will get something like :

cat ~/.ssh/id_rsa.pub 

ssh-rsa AAAB3NzaC1yc2EAAAADAQABAAACAQCvMzmFEUPvaA1AFEBH6zGIF3N6pVE2SJv9V1MHgEwk4C7xovdk7Lr4LDoqEcqxgeJftwWQWWVrWWf7q9qCdHTAanH2Q5vx5nZjLB+B7saksehVOPWDR/MOSpVcr5bwIjf8dc8u5S8h24uBlguGkX+4lFJ+zwhiuwJlhykMvs5py1gD2hy+hvOs1Y17JPWhVVesGV3tlmtbfVolEiv9KShgkk3Hq56fyl+QmPzX1jya4TIC3k55FTzwRWBd+IpblbrGlrIBS6hvpHQpgUs47nSHLEHTn0Xmn6Q== [email protected]

copy this key (value) and go to github.com and under the setting (ssh and pgp key) add your public key.

As others have mentioned, from C++17 onwards you can make use of structured bindings for multiple variable assignments.

Combining this with std::array and template argument deduction we can write a function that assigns a value to an arbitrary number of variables without repeating the type or value.

#include <iostream>
#include <array>

template <int N, typename T> auto assign(T value)
{
    std::array<T, N> out;
    out.fill(value);
    return out;
}

int main()
{
    auto [a, b, c] = assign<3>(1);

    for (const auto& v : {a, b, c})
    {
        std::cout << v << std::endl;
    }

    return 0;
}

I've been looking into this problem for myself for almost a day and finally had a breakthrough. Try this:

1. Setting the PYTHONPATH / PYTHONHOME variables

   Right click the Computer icon in the start menu, go to properties. On the left tab, go to Advanced system settings. In the window that comes up, go to the Advanced tab, then at the bottom click Environment Variables. Click in the list of user variables and start typing Python, and repeat for System variables, just to make certain that you don't have mis-set variables for PYTHONPATH or PYTHONHOME. Next, add new variables (I did in System rather than User, although it may work for User too): PYTHONPATH, set to C:\Python27\Lib. PYTHONHOME, set to C:\Python27.

Hope this helps!

You don't need EXEC clause. Simply use

proc_name paramValue1, paramValue2

(and you need commas as Misnomer mentioned)

In the CMakeLists.txt file, create a cache variable, as documented here:

SET(FAB "po" CACHE STRING "Some user-specified option")

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#command:set

Then, either use the GUI (ccmake or cmake-gui) to set the cache variable, or specify the value of the variable on the cmake command line:

cmake -DFAB:STRING=po

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#opt:-Dvar:typevalue

Modify your cache variable to a boolean if, in fact, your option is boolean.

this is old but, use nano, vim or gvim

I had the same problem, and I found the solution in this post of Sam Goddard,

The solution if to defined the call to the font twice. First as it is recommended, to be used for all the browsers, and after a particular call only for Chrome with a special media query:

@font-face {
  font-family: 'chunk-webfont';
  src: url('../../includes/fonts/chunk-webfont.eot');
  src: url('../../includes/fonts/chunk-webfont.eot?#iefix') format('eot'),
  url('../../includes/fonts/chunk-webfont.woff') format('woff'),
  url('../../includes/fonts/chunk-webfont.ttf') format('truetype'),
  url('../../includes/fonts/chunk-webfont.svg') format('svg');
  font-weight: normal;
  font-style: normal;
}

@media screen and (-webkit-min-device-pixel-ratio:0) {
  @font-face {
    font-family: 'chunk-webfont';
    src: url('../../includes/fonts/chunk-webfont.svg') format('svg');
  }
}

With this method the font will render good in all browsers. The only negative point that I found is that the font file is also downloaded twice.

How about this for instance :

var youtubeimgsrc = document.getElementById("youtubeimg").getAttribute('src');

You can use requestPermissions(PERMISSIONS, MULTIPLE_PERMISSIONS_CODE);. Do not use FragmentCompat if you are using v4.

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

You should be able to attach an event handler to the onchange event of the input and have that call a function to set the text in your span.

<script type="text/javascript">
  $(function() {
     $("input:file").change(function (){
       var fileName = $(this).val();
       $(".filename").html(fileName);
     });
  });
</script>

You may want to add IDs to your input and span so you can select based on those to be specific to the elements you are concerned with and not other file inputs or spans in the DOM.

You can just as easily access each element in the list using e.g. path[[1]]. You can't put a set of matrices into an atomic vector and access each element. A matrix is an atomic vector with dimension attributes. I would use the list structure returned by split, it's what it was designed for. Each list element can hold data of different types and sizes so it's very versatile and you can use *apply functions to further operate on each element in the list. Example below.

#  For reproducibile data
set.seed(1)

#  Make some data
userid <- rep(1:2,times=4)
data1 <- replicate(8 , paste( sample(letters , 3 ) , collapse = "" ) )
data2 <- sample(10,8)
df <- data.frame( userid , data1 , data2 )

#  Split on userid
out <- split( df , f = df$userid )
#$`1`
#  userid data1 data2
#1      1   gjn     3
#3      1   yqp     1
#5      1   rjs     6
#7      1   jtw     5

#$`2`
#  userid data1 data2
#2      2   xfv     4
#4      2   bfe    10
#6      2   mrx     2
#8      2   fqd     9

Access each element using the [[ operator like this:

out[[1]]
#  userid data1 data2
#1      1   gjn     3
#3      1   yqp     1
#5      1   rjs     6
#7      1   jtw     5

Or use an *apply function to do further operations on each list element. For instance, to take the mean of the data2 column you could use sapply like this:

sapply( out , function(x) mean( x$data2 ) )
#   1    2 
#3.75 6.25 

Use =concatenate(). Concatenate is generally used to combine the words of several cells into one, but if you only input one cell it will return that value. There are other methods, but I find this is the best because it is the only method that works when a formula, whose value you wish to return, is in a merged cell.

To be safe you don't break stuff (for example when these strings are changed in your code or further up), or crash you program (in case the returned string was literal for example like "hello I'm a literal string" and you start to edit it), make a copy of the returned string.

You could use strdup() for this, but read the small print. Or you can of course create your own version if it's not there on your platform.

In your Info.plist, Right click in the properties table, click Add Row, add key name App Uses Non-Exempt Encryption with Type Boolean and set value NO.

Read this thread R - boolean operators && and ||.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

$(document).on('keyup','#search_product',function(){
    $( "#search_product" ).autocomplete({
      source:function(request,response){
                  $.post("<?= base_url('ecommerce/autocomplete') ?>",{'name':$( "#search_product" ).val()}).done(function(data, status){

                    response(JSON.parse(data));
        });
      }
    });
});

PHP code :

public function autocomplete(){
    $name=$_POST['name'];
    $result=$this->db->select('product_name,sku_code')->like('product_name',$name)->get('product_list')->result_array();
    $names=array();
    foreach($result as $row){
        $names[]=$row['product_name'];
    }
    echo json_encode($names);
}

table tr td:nth-child(2) {
    background: #ccc;

You need to link with the math library, libm:

$ gcc -Wall foo.c -o foo -lm 

Derived from the answer of @SilentGhost I would use:

Check out this interactive regexr.com page to see the result and explanation for the suggested solution.

You don't need to encode data that is already encoded. When you try to do that, Python will first try to decode it to unicode before it can encode it back to UTF-8. That is what is failing here:

>>> data = u'\u00c3'            # Unicode data
>>> data = data.encode('utf8')  # encoded to UTF-8
>>> data
'\xc3\x83'
>>> data.encode('utf8')         # Try to *re*-encode it
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

Just write your data directly to the file, there is no need to encode already-encoded data.

If you instead build up unicode values instead, you would indeed have to encode those to be writable to a file. You'd want to use codecs.open() instead, which returns a file object that will encode unicode values to UTF-8 for you.

You also really don't want to write out the UTF-8 BOM, unless you have to support Microsoft tools that cannot read UTF-8 otherwise (such as MS Notepad).

For your MySQL insert problem, you need to do two things:

• Add charset='utf8' to your MySQLdb.connect() call.

• Use unicode objects, not str objects when querying or inserting, but use sql parameters so the MySQL connector can do the right thing for you:

  artiste = artiste.decode('utf8')  # it is already UTF8, decode to unicode
  
  c.execute('SELECT COUNT(id) AS nbr FROM artistes WHERE nom=%s', (artiste,))
  
  # ...
  
  c.execute('INSERT INTO artistes(nom,status,path) VALUES(%s, 99, %s)', (artiste, artiste + u'/'))
  

It may actually work better if you used codecs.open() to decode the contents automatically instead:

import codecs

sql = mdb.connect('localhost','admin','ugo&(-@F','music_vibration', charset='utf8')

with codecs.open('config/index/'+index, 'r', 'utf8') as findex:
    for line in findex:
        if u'#artiste' not in line:
            continue

        artiste=line.split(u'[:::]')[1].strip()

    cursor = sql.cursor()
    cursor.execute('SELECT COUNT(id) AS nbr FROM artistes WHERE nom=%s', (artiste,))
    if not cursor.fetchone()[0]:
        cursor = sql.cursor()
        cursor.execute('INSERT INTO artistes(nom,status,path) VALUES(%s, 99, %s)', (artiste, artiste + u'/'))
        artists_inserted += 1

You may want to brush up on Unicode and UTF-8 and encodings. I can recommend the following articles:

• The Python Unicode HOWTO

• Pragmatic Unicode by Ned Batchelder

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky

Probably this is not the best of solution but doing the following will solve the problem

Step 1: Take a database dump using the following command

mysqldump -u root -p databaseName > databaseName.db

find the line

ENGINE=InnoDB AUTO_INCREMENT="*****" DEFAULT CHARSET=utf8;

Step 2: Change ******* to max id of your mysql table id. Save this value.

Step 3: again use

mysql -u root -p databaseName < databaseName.db

In my case i got this error when i added a manual entry to use to enter data into some other table. some how we have to set the value AUTO_INCREMENT to max id using mysql command

For those using something like babel stage-2 or transform-class-properties:

import React, { PropTypes, Component } from 'react';

export default class ExampleComponent extends Component {
   static contextTypes = {
      // some context types
   };

   static propTypes = {
      prop1: PropTypes.object
   };

   static defaultProps = {
      prop1: { foobar: 'foobar' }
   };

   ...

}

Update

As of React v15.5, PropTypes was moved out of the main React Package (link):

import PropTypes from 'prop-types';

Edit

As pointed out by @johndodo, static class properties are actually not a part of the ES7 spec, but rather are currently only supported by babel. Updated to reflect that.

You should be able to transfer the Application to another Username. You would need all your old user information to transfer it. The application would remove it's self from old account to new account. Also you could put a limit on how many times you where allowed to transfer it. If you transfer it to the application could expire after a year and force to buy update.

No, you shouldn't call it explicitly because it would be called twice. Once for the manual call and another time when the scope in which the object is declared ends.

Eg.

{
  Class c;
  c.~Class();
}

If you really need to perform the same operations you should have a separate method.

There is a specific situation in which you may want to call a destructor on a dynamically allocated object with a placement new but it doesn't sound something you will ever need.

try this

 data => {
                this.results = [...this.results, ...data.results];
                this._next = data.next;
            }

You can use, pathlib also

from pathlib import Path

fl = Path("file_name")

fl.chmod(0o444)

This will do it:

my_hash.each_with_object({}) { |(key, value), hash| hash[key] = value.upcase }

As opposed to inject the advantage is that you are in no need to return the hash again inside the block.

Some languages have combining diacritics as language letters and accent diacritics to specify accent.

I think it is more safe to specify explicitly what diactrics you want to strip:

def strip_accents(string, accents=('COMBINING ACUTE ACCENT', 'COMBINING GRAVE ACCENT', 'COMBINING TILDE')):
    accents = set(map(unicodedata.lookup, accents))
    chars = [c for c in unicodedata.normalize('NFD', string) if c not in accents]
    return unicodedata.normalize('NFC', ''.join(chars))

In ASP.NET Core the IJsonHelper.Serialize() returns IHtmlContent so you don't need to wrap it with a call to Html.Raw().

It should be as simple as:

<script>
  var json = @Json.Serialize(Model.CollegeInformationlist);
</script>

I would suggest using conda. Conda is an anconda specific package manager. If you want to know more about conda, read the conda docs.

Using conda in the command line, the command below would install scipy 0.17.

conda install scipy=0.17.0

_{Since nobody has mentioned this..}

Modern Approach:

As an alternative to setting both the html/body element's heights to 100%, you could also use viewport-percentage lengths:

5.1.2. Viewport-percentage lengths: the ‘vw’, ‘vh’, ‘vmin’, ‘vmax’ units

The viewport-percentage lengths are relative to the size of the initial containing block. When the height or width of the initial containing block is changed, they are scaled accordingly.

In this instance, you could use the value 100vh (which is the height of the viewport) - (example)

body {
    height: 100vh;
}

Setting a min-height also works. (example)

body {
    min-height: 100vh;
}

These units are supported in most modern browsers - support can be found here.

Change your configuration to this (add a slash):

RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule (.*) http://www.example.com/$1 [R=301,L] 

Or the solution outlined below (proposed by @absiddiqueLive) will work for any domain:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

If you need to support http and https and preserve the protocol choice try the following:

RewriteRule ^login\$ https://www.%{HTTP_HOST}/login [R=301,L]

Where you replace login with checkout.php or whatever URL you need to support HTTPS on.

I'd argue this is a bad idea though. For the reasoning please read this answer.

For a certain column, if you don't care about the ordering, use this

df['col1_num'] = df['col1'].apply(lambda x: np.where(df['col1'].unique()==x)[0][0])

If you care about the ordering, specify them as a list and use this

df['col1_num'] = df['col1'].apply(lambda x: ['first', 'second', 'third'].index(x))

You can use the method UrlEncodedFormEntity.writeTo(OutputStream).

UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(nvp); 
http.connect();

OutputStream output = null;
try {
  output = http.getOutputStream();    
  formEntity.writeTo(output);
} finally {
 if (output != null) try { output.close(); } catch (IOException ioe) {}
}

How about the SQuirreL SQL Client? As mentioned in another SO question, this programs has the capability to generate a simple ER diagram.

Just update @angular/material from 7 to 9,

npm uninstall @angular/material --save

Include using namespace System.Linq

List<string> stringList = line.Split(',').ToList();

you can make use of it with ease for iterating through each item.

foreach(string str in stringList)
{

}

String.Split() returns an array, hence convert it to a list using ToList()

Use the Controller's Redirect() method.

public ActionResult YourAction()
{
    // ...
    return Redirect("http://www.example.com");
}

Update

You can't directly perform a server side redirect from an ajax response. You could, however, return a JsonResult with the new url and perform the redirect with javascript.

public ActionResult YourAction()
{
    // ...
    return Json(new {url = "http://www.example.com"});
}

$.post("@Url.Action("YourAction")", function(data) {
    window.location = data.url;
});

Try using the passive command before using ls.

From FTP client, to check if the FTP server supports passive mode, after login, type quote PASV.

Following are connection examples to a vsftpd server with passive mode on and off

vsftpd with pasv_enable=NO:

# ftp localhost

220 (vsFTPd 2.3.5)
Name (localhost:john): anonymous
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> quote PASV
550 Permission denied.

vsftpd with pasv_enable=YES:

# ftp localhost
Connected to localhost.localdomain.
220 (vsFTPd 2.3.5)

Debian 9 solution:

touch /etc/apache2/conf-available/php.conf 

Add to file next lines:

<IfModule mod_php5.c>
    <IfModule mod_mime.c>
        AddType application/x-httpd-php .php
    </IfModule>
    <FilesMatch ".+\.php$">
        SetHandler application/x-httpd-php
    </FilesMatch>
</IfModule>
<IfModule mod_php.c>
    <IfModule mod_mime.c>
        AddType application/x-httpd-php .php
    </IfModule>
    <FilesMatch ".+\.php$">
        SetHandler application/x-httpd-php
    </FilesMatch>
</IfModule>

Then run:

a2enconf php && service apache2 restart

It's a consequence of the size of the exponent part of the type, as in IEEE 754 for example. You can examine the sizes with FLT_MAX, FLT_MIN, DBL_MAX, DBL_MIN in float.h.

enctype='multipart/form-data is an encoding type that allows files to be sent through a POST. Quite simply, without this encoding the files cannot be sent through POST.

If you want to allow a user to upload a file via a form, you must use this enctype.

Here are some vendors you might me looking for

::-webkit-input-placeholder {color: tomato}
::-moz-placeholder          {color: tomato;} /* Firefox 19+ */
:-moz-placeholder           {color: tomato;} /* Firefox 18- */
:-ms-input-placeholder      {color: tomato;}

You can also style different states, such as focus

:focus::-webkit-input-placeholder {color: transparent}
:focus::-moz-placeholder          {color: transparent}
:focus:-moz-placeholder           {color: transparent}
:focus:-ms-input-placeholder      {color: transparent}

You can also do certain transitions on it, like

::-VENDOR-input-placeholder       {text-indent: 0px;   transition: text-indent 0.3s ease;}
:focus::-VENDOR-input-placeholder  {text-indent: 500px; transition: text-indent 0.3s ease;}

Lower mm means minutes, so

DateTime.Now.ToString("dd/MM/yyyy");  

or

DateTime.Now.ToString("d");  

or

DateTime.Now.ToShortDateString()

works.

Standard Date and Time Format Strings

You can use:

function encodeHTML(str){
 var aStr = str.split(''),
     i = aStr.length,
     aRet = [];

   while (i--) {
    var iC = aStr[i].charCodeAt();
    if (iC < 65 || iC > 127 || (iC>90 && iC<97)) {
      aRet.push('&#'+iC+';');
    } else {
      aRet.push(aStr[i]);
    }
  }
 return aRet.reverse().join('');
}

This function HTMLEncodes everything that is not a-z/A-Z.

[Edit] A rather old answer. Let's add a simpler String extension to encode all extended characters:

String.prototype.encodeHTML = function () {
  return this.replace(/[\u0080-\u024F]/g, 
          function (v) {return '&#'+v.charCodeAt()+';';}
         );
}
// usage
log('Übergroße Äpfel mit Würmern'.encodeHTML());
//=> 'Übergroße Äpfel mit Würmern'

I've used a "breakout" pattern for this:

$(sentences).each(function() {
    var breakout;
    var s = this;
    alert(s);
    $(words).each(function(i) {
        if (s.indexOf(this) > -1)
        {
            alert('found ' + this);
            return breakout = false;
        }
    });
    return breakout;
});

This works nicely to any nesting depth. breakout is a simple flag. It will stay undefined unless and until you set it to false (as I do in my return statement as illustrated above). All you have to do is:

1. declare it in your outermost closure: var breakout;
2. add it to your return false statement(s): return breakout = false
3. return breakout in your outer closure(s).

Not too inelegant, right? ...works for me anyway.

My problem was dotnet got hung up and whenever VS would try to make a new dll, or access an old one, the dotnet process would latch onto the dll and stop visual studio from cloning the dll. Solution is just to end all dotnet tasks in task manager(it will only actually remove the dead one, if you are trying to end one and it won't shut down, that means it's working).

$http_name_of_the_header_key

i.e if you have origin = domain.com in header, you can use $http_origin to get "domain.com"

In nginx does support arbitrary request header field. In the above example last part of a variable name is the field name converted to lower case with dashes replaced by underscores

Reference doc here: http://nginx.org/en/docs/http/ngx_http_core_module.html#var_http_

For your example the variable would be $http_my_custom_header.

>> strs = {'HA' 'KU' 'LA' 'MA' 'TATA'};
>> tic; ind=find(ismember(strs,'KU')); toc

Elapsed time is 0.001976 seconds.

>> tic; find(strcmp('KU', strs)); toc

Elapsed time is 0.000014 seconds.

SO, clearly strcmp('KU', strs) takes much lesser time than ismember(strs,'KU')

Make sure you change the right info.plist file.

This is the second time I waste time on this issue, because I didn't notice that I'm changing info.plist under MyProjectNameUITests.

you can use list comprehensions to do this in a single line

n = 4
chunks = [df[i:i+n] for i in range(0,df.shape[0],n)]

You don't have to use key attribute all the time. Make sure the mapping file properly addressed the key

this.HasKey(t => t.Key);
this.ToTable("PacketHistory");
this.Property(p => p.Key)
            .HasColumnName("PacketHistorySK");

and don't forget to add the mapping in the Repository's OnModelCreating

modelBuilder.Configurations.Add(new PacketHistoryMap());

string result = Regex.Replace(anytext, @"<(.|\n)*?>", string.Empty);

I believe the intention is for the script in question to fail fast.

To test this yourself, simply type set -e at a bash prompt. Now, try running ls. You'll get a directory listing. Now, type lsd. That command is not recognized and will return an error code, and so your bash prompt will close (due to set -e).

Now, to understand this in the context of a 'script', use this simple script:

#!/bin/bash 
# set -e

lsd 

ls

If you run it as is, you'll get the directory listing from the ls on the last line. If you uncomment the set -e and run again, you won't see the directory listing as bash stops processing once it encounters the error from lsd.

If you are talking about the scrollbar that automatically appears on a div with overflow: scroll (or auto), then no, that's still a native scrollbar rendered by the browser using normal OS widgets, and not something that can be styled(*).

Whilst you can replace it with a proxy made out of stylable divs and JavaScript as suggested by Matt, I wouldn't recommend it for the general case. Script-driven scrollbars never quite behave exactly the same as real OS scrollbars, causing usability and accessibility problems.

(*: Except for the IE colouring styles, which I wouldn't really recommend either. Apart from being IE-only, using them forces IE to fall back from using nice scrollbar images from the current Windows theme to ugly old Win95-style scrollbars.)

Gmail: OAuth

• Goto the link
• Login with your gmail username password
• Click on the google menu at the top left
• Click API Manager
• Click on Credentials
• Click Create Credentials and select OAuth Client
• Select Web Application as Application type and Enter the Name-> Enter Authorised Redirect URL (Eg: http://localhost:53922/signin-google) ->Click on Create button. This will create the credentials. Pls make a note of Client ID and Secret ID. Finally click OK to close the credentials pop up.
• Next important step is to enable the Google API. Click on Overview in the left pane.
• Click on the Google API under Social APIs section.
• Click Enable.

That’s all from the Google part.

Come back to your application, open App_start/Startup.Auth.cs and uncomment the following snippet

        app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
        {
            ClientId = "",
            ClientSecret = ""
        });

Update the ClientId and ClientSecret with the values from Google API credentials which you have created already.

• Run your application
• Click Login
• You will see the Google button under ‘Use Another Section to log in’ section
• Click on the Google button
• Application will prompt you to enter the username and password
• Enter the gmail username and password and click Sign In
• This will perform the OAuth and come back to your application and prompting you to register with the Gmail id.
• Click register to register the Gmail id into your application database.
• You will see the Identity details appear in the top as normal registration
• Try logout and login again thru Gmail. This will automatically logs you into the app.

Let's look at both ways:

(function(){
    var i2 = i;
    setTimeout(function(){
        console.log(i2);
    }, 1000)
})();

Declares and immediately executes an anonymous function that runs setTimeout() within its own context. The current value of i is preserved by making a copy into i2 first; it works because of the immediate execution.

setTimeout((function(i2){
    return function() {
        console.log(i2);
    }
})(i), 1000);

Declares an execution context for the inner function whereby the current value of i is preserved into i2; this approach also uses immediate execution to preserve the value.

Important

It should be mentioned that the run semantics are NOT the same between both approaches; your inner function gets passed to setTimeout() whereas his inner function calls setTimeout() itself.

Wrapping both codes inside another setTimeout() doesn't prove that only the second approach uses closures, there's just not the same thing to begin with.

Conclusion

Both methods use closures, so it comes down to personal taste; the second approach is easier to "move" around or generalize.

A bit late to the party, but Krux has created a script for this, called Postscribe. We were able to use this to get past this issue.

Justin's answer did not work for me (Chromium 18, Firefox 43.0.1). jQuery's .focus() creates visual highlight, but text cursor does not appear in the field (jquery 3.1.0).

Inspired by https://www.sitepoint.com/jqueryhtml5-input-focus-cursor-positions/ , I added autofocus attribute to the input field and voila!

function addfield() {
    n=$('table tr').length;
    $('table').append('<tr><td><input name=field'+n+' autofocus></td><td><input name=value'+n+'></td></tr>');
    $('input[name="aa"'+n+']').focus();
}

you can use DATEADD function in your where clause like

select ...... where Createdate >= DATEADD(day,-7,GETDATE())

I was trying to resolve it like the other answers unfortunately, I didn't get a right way to do it, once I tried as I write below:

$('#<%=ddID.ClientID %>').get(0).selectedIndex = 0;

this code works for me, I hope that will be useful for you guys.

While we are up to setting JAVA_HOME, let me share some benefits of setting JAVA_HOME or any other environment variable:

1) It's easy to upgrade JDK without affecting your application startup and config file which points to JAVA_HOME. you just need to download new version and make sure your JAVA_HOME points to new version of Java. This is best benefit of using environment variable or links.

2) JAVA_HOME variable is short and concise instead of full path to JDK installation directory.

3) JAVA_HOME variable is platform independence i.e. if your startup script uses JAVA_HOME then it can run on Windows and UNIX without any modification, you just need to set JAVA_HOME on respective operating system.

precision: Its the total number of digits before or after the radix point. EX: 123.456 here precision is 6.

Scale: Its the total number of digits after the radix point. EX: 123.456 here Scaleis 3

In case you are using the annotation method for filter definition (as opposed to defining them in the web.xml), you can do so by just putting an array of mappings in the @WebFilter annotation:

/**
 * Filter implementation class LoginFilter
 */
@WebFilter(urlPatterns = { "/faces/Html/Employee","/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginFilter implements Filter {
    ...

And just as an FYI, this same thing works for servlets using the servlet annotation too:

/**
 * Servlet implementation class LoginServlet
 */
@WebServlet({"/faces/Html/Employee", "/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginServlet extends HttpServlet {
    ...

The first case will fail when JS is off. It's also a little bit slower since JS must be parsed first (DOM must be loaded). However JS is safer since the destination doesn't know the referer and your redirect might be tracked (referers aren't reliable in general yet this is something).

You can also use meta refresh tag. It also requires DOM to be loaded.

Managed to get the input field value by doing something like this:

import React, { Component } from 'react';

class App extends Component {

constructor(props){
super(props);

this.state = {
  username : ''
}

this.updateInput = this.updateInput.bind(this);

The comparison needs to be evaluated fully inside EL ${ ... }, not outside.

<c:if test="${values.type eq 'object'}">

As to the docs, those ${} things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.

<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

• Our EL wiki page

By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass() and then Class#getSimpleName() instead of adding a custom getter.

<c:forEach items="${list}" var="value">
    <c:if test="${value['class'].simpleName eq 'Object'}">
        <!-- code here -->
    </c:if>
</c:forEeach>

The answers at the other link will work, but to serve out HTML, there is no need to use a view engine at all, unless you want to set up funky routing. Instead, just use the static middleware:

app.use(express.static(__dirname + '/public'));

If you are using VB as code behind, you have to use bracket "()" instead of square bracket "[]".

Example for VB:

<script type="text/javascript">
var accesslevel = '<%= Session("accesslevel").ToString().ToLower() %>';
</script>  

List<string> lines = new List<string>();
 using (var sr = new StreamReader("file.txt"))
 {
      while (sr.Peek() >= 0)
          lines.Add(sr.ReadLine());
 }

i would suggest this... of Groo's answer.

One package that is very likely to be installed on a system already is python-lxml. If so, this is possible without installing any extra package:

python -c "from lxml.etree import parse; from sys import stdin; print('\n'.join(parse(stdin).xpath('//element/@attribute')))"

I would consinder enclosing that select block within a div block and setting the border property like this:

<div style="border: 2px solid blue;">_x000D_
  <select style="width: 100%;">_x000D_
    <option value="Sal">Sal</option>_x000D_
    <option value="Awesome">Awesome!</option>_x000D_
  </select>_x000D_
</div>

You should be able to play with that to accomplish what you need.

If you use Kotlin another solution could be just create extension function for Response class:

inline fun <reified T>Response<*>.parseErrJsonResponse(): T?
{
    val moshi = MyCustomMoshiBuilder().build()
    val parser = moshi.adapter(T::class.java)
    val response = errorBody()?.string()
    if(response != null)
        try {
            return parser.fromJson(response)
        } catch(e: JsonDataException) {
            e.printStackTrace()
        }
    return null
}

Usage

val myError = response.parseErrJsonResponse<MyErrorResponse>()
if(myError != null) {
   // handle your error logic here
   // ...
}

Similar situation. It was working. Then, I started to include pytables. At first view, no reason to errors. I decided to use another function, that has a domain constraint (elipse) and received the following error:

TypeError: 'numpy.float64' object cannot be interpreted as an integer

or

TypeError: 'numpy.float64' object is not iterable

The crazy thing: the previous function I was using, no code changed, started to return the same error. My intermediary function, already used was:

def MinMax(x, mini=0, maxi=1)
    return max(min(x,mini), maxi)

The solution was avoid numpy or math:

def MinMax(x, mini=0, maxi=1)
    x = [x_aux if x_aux > mini else mini for x_aux in x]
    x = [x_aux if x_aux < maxi else maxi for x_aux in x]
    return max(min(x,mini), maxi)

Then, everything calm again. It was like one library possessed max and min!

$cat abs.sh
#!/bin/bash
echo "$(cd "$(dirname "$1")"; pwd -P)"

Some explanations:

1. This script get relative path as argument "$1"
2. Then we get dirname part of that path (you can pass either dir or file to this script): dirname "$1"
3. Then we cd "$(dirname "$1"); into this relative dir
4. pwd -P and get absolute path. The -P option will avoid symlinks
5. As final step we echo it

Then run your script:

abs.sh your_file.txt

And if anyone is wondering how to do this in swift:

if let myDelegate = UIApplication.sharedApplication().delegate as? AppDelegate {
   myDelegate.someMethod()
}

Andrey Tarasevich provides the following explanation:

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

After encountering this issue and tried different method of adding the entity packaname name to EntityScan, ComponentScan etc, none of it worked.

Added the package to packageScan config in the EntityManagerFactory of the repository config. The below code gives the code based configuration as opposed to XML based ones answered above.

@Primary
@Bean(name = "entityManagerFactory")
public EntityManagerFactory entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(dataSource);
    emf.setJpaVendorAdapter(jpaVendorAdapter);
    emf.setPackagesToScan("org.package.entity");
    emf.setPersistenceUnitName("default"); 
    emf.afterPropertiesSet();
    return emf.getObject();
}

You need to do something with the return value...

import java.util.Arrays;

public class trial1{

    public static void main(String[] args){
        int[] B = numbers();
        System.out.println(Arrays.toString(B));
    }

    public static int[] numbers(){
        int[] A = {1,2,3};
        return A;
    }
}

Simple line below works just fine:

header("Location: ?");

As Andy said the document will be not valid, but nevertheless the script will still be interpreted. See the snippet from WebKit for example:

void HTMLParser::processCloseTag(Token* t)
{
    // Support for really broken html.
    // we never close the body tag, since some stupid web pages close it before 
    // the actual end of the doc.
    // let's rely on the end() call to close things.
    if (t->tagName == htmlTag || t->tagName == bodyTag 
                              || t->tagName == commentAtom)
        return;
    ...

You may well want to use JSON-P instead (see below). First a quick explanation.

The header you've mentioned is from the Cross Origin Resource Sharing standard. Beware that it is not supported by some browsers people actually use, and on other browsers (Microsoft's, sigh) it requires using a special object (XDomainRequest) rather than the standard XMLHttpRequest that jQuery uses. It also requires that you change server-side resources to explicitly allow the other origin (www.xxxx.com).

To get the JSON data you're requesting, you basically have three options:

1. If possible, you can be maximally-compatible by correcting the location of the files you're loading so they have the same origin as the document you're loading them into. (I assume you must be loading them via Ajax, hence the Same Origin Policy issue showing up.)

2. Use JSON-P, which isn't subject to the SOP. jQuery has built-in support for it in its ajax call (just set dataType to "jsonp" and jQuery will do all the client-side work). This requires server side changes, but not very big ones; basically whatever you have that's generating the JSON response just looks for a query string parameter called "callback" and wraps the JSON in JavaScript code that would call that function. E.g., if your current JSON response is:

   {"weather": "Dreary start but soon brightening into a fine summer day."}
   

   Your script would look for the "callback" query string parameter (let's say that the parameter's value is "jsop123") and wraps that JSON in the syntax for a JavaScript function call:

   jsonp123({"weather": "Dreary start but soon brightening into a fine summer day."});
   

   That's it. JSON-P is very broadly compatible (because it works via JavaScript script tags). JSON-P is only for GET, though, not POST (again because it works via script tags).

3. Use CORS (the mechanism related to the header you quoted). Details in the specification linked above, but basically:

   A. The browser will send your server a "preflight" message using the OPTIONS HTTP verb (method). It will contain the various headers it would send with the GET or POST as well as the headers "Origin", "Access-Control-Request-Method" (e.g., GET or POST), and "Access-Control-Request-Headers" (the headers it wants to send).

   B. Your PHP decides, based on that information, whether the request is okay and if so responds with the "Access-Control-Allow-Origin", "Access-Control-Allow-Methods", and "Access-Control-Allow-Headers" headers with the values it will allow. You don't send any body (page) with that response.

   C. The browser will look at your response and see whether it's allowed to send you the actual GET or POST. If so, it will send that request, again with the "Origin" and various "Access-Control-Request-xyz" headers.

   D. Your PHP examines those headers again to make sure they're still okay, and if so responds to the request.

   In pseudo-code (I haven't done much PHP, so I'm not trying to do PHP syntax here):

   // Find out what the request is asking for
   corsOrigin = get_request_header("Origin")
   corsMethod = get_request_header("Access-Control-Request-Method")
   corsHeaders = get_request_header("Access-Control-Request-Headers")
   if corsOrigin is null or "null" {
       // Requests from a `file://` path seem to come through without an
       // origin or with "null" (literally) as the origin.
       // In my case, for testing, I wanted to allow those and so I output
       // "*", but you may want to go another way.
       corsOrigin = "*"
   }
   
   // Decide whether to accept that request with those headers
   // If so:
   
   // Respond with headers saying what's allowed (here we're just echoing what they
   // asked for, except we may be using "*" [all] instead of the actual origin for
   // the "Access-Control-Allow-Origin" one)
   set_response_header("Access-Control-Allow-Origin", corsOrigin)
   set_response_header("Access-Control-Allow-Methods", corsMethod)
   set_response_header("Access-Control-Allow-Headers", corsHeaders)
   if the HTTP request method is "OPTIONS" {
       // Done, no body in response to OPTIONS
       stop
   }
   // Process the GET or POST here; output the body of the response
   

   Again stressing that this is pseudo-code.

Redis supports 5 data types. You need to know what type of value that a key maps to, as for each data type, the command to retrieve it is different.

Here are the commands to retrieve key value:

• if value is of type string -> GET <key>
• if value is of type hash -> HGETALL <key>
• if value is of type lists -> lrange <key> <start> <end>
• if value is of type sets -> smembers <key>
• if value is of type sorted sets -> ZRANGEBYSCORE <key> <min> <max>

Use the TYPE command to check the type of value a key is mapping to:

• type <key>

Some cases where I have found it useful:

• mark a test that is incomplete, so it fails and warns you until you can finish it
• making sure an exception is thrown:

try{
  // do stuff...
  fail("Exception not thrown");
}catch(Exception e){
  assertTrue(e.hasSomeFlag());
}

Note:

Since JUnit4, there is a more elegant way to test that an exception is being thrown: Use the annotation @Test(expected=IndexOutOfBoundsException.class)

However, this won't work if you also want to inspect the exception, then you still need fail().

Just check whether the commons-logging.jar has been added to your libs and the classpath.. I had the same issue and that was because of this. dhammikas-

I was looking for a way to do this too and found this, could be useful for other people:

#table td:last-of-type { border: none; }

the above solutions wont work on ipad-2

recently I had an safari browser crash issue while plotting the markers even if there are less number of markers. Initially I was using marker with label (markerwithlabel.js) library for plotting the marker , when i use google native marker it was working fine even with large number of markers but i want customized markers , so i refer the above solution given by jonathan but still the crashing issue is not resolved after doing lot of research i came to know about http://nickjohnson.com/b/google-maps-v3-how-to-quickly-add-many-markers this blog and now my map search is working smoothly on ipad-2 :)

The Javadoc generation can be skipped by setting the property maven.javadoc.skip to true [1], i.e.

-Dmaven.javadoc.skip=true

(and not false)

My favorite way is:

df = df[0:0] 

Try this from different folder:

sudo tar -cvjSf folder.tar.bz2 folder/*

As Oriol said, you need the following redistributables before installing WAMP.

From the readme.txt

BEFORE proceeding with the installation of Wampserver, you must ensure that certain elements are installed on your system, otherwise Wampserver will absolutely not run, and in addition, the installation will be faulty and you need to remove Wampserver BEFORE installing the elements that were missing.

Make sure you are "up to date" in the redistributable packages VC9, VC10, VC11, VC13 and VC14 Even if you think you are up to date, install each package as administrator and if message "Already installed", validate Repair.

The following packages (VC9, VC10, VC11) are imperatively required to Wampserver 2.4, 2.5 and 3.0, even if you use only Apache and PHP versions VC11 and VC14 is required for PHP 7 and Apache 2.4.17

JSON doesn't accept circular objects - objects which reference themselves. JSON.stringify() will throw an error if it comes across one of these.

The request (req) object is circular by nature - Node does that.

In this case, because you just need to log it to the console, you can use the console's native stringifying and avoid using JSON:

console.log("Request data:");
console.log(req);

Your data types are mismatched when you are retrieving the field values. Check your code and ensure that for each field that you are retrieving that the java object matches that type. For example, retrieving a date into and int. If you are doing a select * then it is possible a change in the fields of the table has happened causing this error to occur. Your SQL should only select the fields you specifically want in order to avoid this error.

Hope this helps.

Your data may not be what you expect -- it seems you're expecting, but not getting, floats.

A simple solution to figuring out where this occurs would be to add a try/except to the for-loop:

for i in range(0,N):
    w=f[i].split()
    l1=w[1:8]
    l2=w[8:15]
    try:
      list1=[float(x) for x in l1]
      list2=[float(x) for x in l2]
    except ValueError, e:
      # report the error in some way that is helpful -- maybe print out i
    result=stats.ttest_ind(list1,list2)
    print result[1]

In addition to @RaGe's answer may be the situation I faced where i had a global git ignore that was ignoring .jar files and so the gradle wrapper jar was never being committed. Thus I was getting that error on the Jenkins server after an attempted /var/lib/jenkins/my_project/gradlew build. I had to explicitly force an add of the jar and then commit:

git add -f gradle/wrapper/gradle-wrapper.jar

If you go to TextFX menu and go to TextFX Edit, you will see a menu item Reindent C++ Code.

That will also format C# code.

The problem almost always has something to do with "nested" z-indexes. As an Example:

<div style="z-index:1">
  some content A
  <div style="z-index:1000000000">
    some content B
  </div>
</div>
<div style="z-index:10">
  Some content C
</div>

if you look at the z-index only you would expect B,C,A, but because B is nested in a div that is expressly set to 1, it will show up as C,B,A.

Setting position:fixed locks the z-index for that element and all its children, which is why changing that can solve the problem.

The solution is to find the parent element that has the z-index set and either adjust the setting or move the content so the layers and their parent containers stack up the way you want. Firebug in Firefox has a tab in the far right named "Layout" and you can quickly go up the parent elements and see where the z-index is set.

Here is the version that I used:

typedef enum { false = 0, true = !false } bool;

Because false only has one value, but a logical true could have many values, but technique sets true to be what the compiler will use for the opposite of false.

This takes care of the problem of someone coding something that would come down to this:

if (true == !false)

I think we would all agree that that is not a good practice, but for the one time cost of doing "true = !false" we eliminate that problem.

[EDIT] In the end I used:

typedef enum { myfalse = 0, mytrue = !myfalse } mybool;

to avoid name collision with other schemes that were defining true and false. But the concept remains the same.

[EDIT] To show conversion of integer to boolean:

mybool somebool;
int someint = 5;
somebool = !!someint;

The first (right most) ! converts the non-zero integer to a 0, then the second (left most) ! converts the 0 to a myfalse value. I will leave it as an exercise for the reader to convert a zero integer.

[EDIT] It is my style to use the explicit setting of a value in an enum when the specific value is required even if the default value would be the same. Example: Because false needs to be zero I use false = 0, rather than false,

This is a side note if one still can't access localhost from another devices after following through the step above. This might be due to the apache ports.conf has been configured to serve locally (127.0.0.1) and not to outside.

check the following, (for ubuntu apache2)

  $ cat /etc/apache2/ports.conf

if the following is set,

NameVirtualHost *:80  
Listen 127.0.0.1:80  

then change it back to default value

NameVirtualHost *:80  
Listen 80  

I don't know if this helps:

suppose you want to run a sql script (test.sql) from the command line:

mysql < test.sql

and the contents of test.sql is something like:

SELECT * FROM information_schema.SCHEMATA;
\! echo "I like to party...";

The console will show something like:

CATALOG_NAME    SCHEMA_NAME            DEFAULT_CHARACTER_SET_NAME      
         def    information_schema     utf8
         def    mysql                  utf8
         def    performance_schema     utf8
         def    sys                    utf8
I like to party...

So you can execute terminal commands inside an sql statement by just using \!, provided the script is run via a command line.

   {
      //do something, string length greater than zero
   }

   }
}

This is a simple example. Hope it helps.

edit: added isset in the event a variable isn't defined like above, it would cause an error, checking to see if its first set at the least will help remove some headache down the road.

No. You'll have to do separate updates:

UPDATE  table
SET ID = 111111259
WHERE ID = 2555

UPDATE  table
SET ID = 111111261
WHERE ID = 2724

UPDATE  table
SET ID = 111111263
WHERE ID = 2021

UPDATE  table
SET ID = 111111264
WHERE ID = 2017

From python tutorial:

Degenerate slice indices are handled gracefully: an index that is too large is replaced by the string size, an upper bound smaller than the lower bound returns an empty string.

So it is safe to use x[:100].

you can use the clip property:

#container {
  position: absolute;
  clip: rect(0px,200px,100px,0px);
  overflow: hidden;
  background: red;
}

note the position: absolute and overflow: hidden needed in order to get clip to work.

As well as all the other reasons already stated, it allows for easier access to overridden methods; you can call Class.some_method(inst).

An example of where it’s useful:

class C1(object):
    def __init__(self):
         print "C1 init"

class C2(C1):
    def __init__(self): #overrides C1.__init__
        print "C2 init"
        C1.__init__(self) #but we still want C1 to init the class too

>>> C2()
"C2 init"
"C1 init"

One more solution as PyV8 seems to be unmaintained and dependent on the old version of libv8.

PyMiniRacer It's a wrapper around the v8 engine and it works with the new version and is actively maintained.

pip install py-mini-racer

from py_mini_racer import py_mini_racer
ctx = py_mini_racer.MiniRacer()
ctx.eval("""
function escramble_758(){
    var a,b,c
    a='+1 '
    b='84-'
    a+='425-'
    b+='7450'
    c='9'
    return a+c+b;
}
""")
ctx.call("escramble_758")

And yes, you have to replace document.write with return as others suggested

str.strip() returns a string with leading+trailing whitespace removed, .lstrip and .rstrip for only leading and trailing respectively.

grades.append(lists[i].rstrip('\n').split(','))

Use the read command:

echo Would you like to install? "(Y or N)"

read x

# now check if $x is "y"
if [ "$x" = "y" ]; then
    # do something here!
fi

and then all of the other stuff you need

You can use this method to pick image from gallery. Only images will be displayed.

public void pickImage() {
    Intent intent = new Intent(Intent.ACTION_PICK,
            MediaStore.Images.Media.INTERNAL_CONTENT_URI);
    intent.setType("image/*");
    intent.putExtra("crop", "true");
    intent.putExtra("scale", true);
    intent.putExtra("outputX", 256);
    intent.putExtra("outputY", 256);
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);
    intent.putExtra("return-data", true);
    startActivityForResult(intent, 1);
}

and override onActivityResult as

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode != RESULT_OK) {
            return;
        }
        if (requestCode == 1) {
            final Bundle extras = data.getExtras();
            if (extras != null) {
                //Get image
                Bitmap newProfilePic = extras.getParcelable("data");
            }
        }
    }

Here's how I would do this:

class ClassPropertyDescriptor(object):

    def __init__(self, fget, fset=None):
        self.fget = fget
        self.fset = fset

    def __get__(self, obj, klass=None):
        if klass is None:
            klass = type(obj)
        return self.fget.__get__(obj, klass)()

    def __set__(self, obj, value):
        if not self.fset:
            raise AttributeError("can't set attribute")
        type_ = type(obj)
        return self.fset.__get__(obj, type_)(value)

    def setter(self, func):
        if not isinstance(func, (classmethod, staticmethod)):
            func = classmethod(func)
        self.fset = func
        return self

def classproperty(func):
    if not isinstance(func, (classmethod, staticmethod)):
        func = classmethod(func)

    return ClassPropertyDescriptor(func)


class Bar(object):

    _bar = 1

    @classproperty
    def bar(cls):
        return cls._bar

    @bar.setter
    def bar(cls, value):
        cls._bar = value


# test instance instantiation
foo = Bar()
assert foo.bar == 1

baz = Bar()
assert baz.bar == 1

# test static variable
baz.bar = 5
assert foo.bar == 5

# test setting variable on the class
Bar.bar = 50
assert baz.bar == 50
assert foo.bar == 50

The setter didn't work at the time we call Bar.bar, because we are calling TypeOfBar.bar.__set__, which is not Bar.bar.__set__.

Adding a metaclass definition solves this:

class ClassPropertyMetaClass(type):
    def __setattr__(self, key, value):
        if key in self.__dict__:
            obj = self.__dict__.get(key)
        if obj and type(obj) is ClassPropertyDescriptor:
            return obj.__set__(self, value)

        return super(ClassPropertyMetaClass, self).__setattr__(key, value)

# and update class define:
#     class Bar(object):
#        __metaclass__ = ClassPropertyMetaClass
#        _bar = 1

# and update ClassPropertyDescriptor.__set__
#    def __set__(self, obj, value):
#       if not self.fset:
#           raise AttributeError("can't set attribute")
#       if inspect.isclass(obj):
#           type_ = obj
#           obj = None
#       else:
#           type_ = type(obj)
#       return self.fset.__get__(obj, type_)(value)

Now all will be fine.

This might be work for you

let main_string = " User not found,Want to review ? Click here"
    let string_to_color = "Click here"

    let range = (main_string as NSString).range(of: string_to_color)

    let attribute = NSMutableAttributedString.init(string: main_string)
    attribute.addAttribute(NSAttributedStringKey.foregroundColor, value: UIColor.blue , range: range)

    lblClickHere.attributedText = attribute

I think if I understand correctly this is what you are doing.

ImageView view = (ImageView) findViewById(R.id.someImage);
view.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View view) {
        ImageView imageView = (ImageView) view;
        assert(R.id.someImage == imageView.getId());

        switch(getDrawableId(imageView)) {
            case R.drawable.foo:
                imageView.setDrawableResource(R.drawable.bar);
                break;
            case R.drawable.bar:
            default:
                imageView.setDrawableResource(R.drawable.foo);
            break;
        }
    });

Right? So that function getDrawableId() doesn't exist. You can't get a the id that a drawable was instantiated from because the id is just a reference to the location of data on the device on how to construct a drawable. Once the drawable is constructed it doesn't have a way to get back the resourceId that was used to create it. But you could make it work something like this using tags

ImageView view = (ImageView) findViewById(R.id.someImage);
view.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View view) {
        ImageView imageView = (ImageView) view;
        assert(R.id.someImage == imageView.getId());

        // See here
        Integer integer = (Integer) imageView.getTag();
        integer = integer == null ? 0 : integer;

        switch(integer) {
        case R.drawable.foo:
            imageView.setDrawableResource(R.drawable.bar);
            imageView.setTag(R.drawable.bar);
            break;
        case R.drawable.bar:
        default:
            imageView.setDrawableResource(R.drawable.foo);
            imageView.setTag(R.drawable.foo);
            break;
        }
    });

This CsvEscape function is XSLT 1.0 and escapes column values ,, ", and newlines like RFC 4180 or Excel. It makes use of the fact that you can recursively call XSLT templates:

• The template EscapeQuotes replaces all double quotes with 2 double quotes, recursively from the start of the string.
• The template CsvEscape checks if the text contains a comma or double quote, and if so surrounds the whole string with a pair of double quotes and calls EscapeQuotes for the string.

Example usage: xsltproc xmltocsv.xslt file.xml > file.csv

You can't create a method swap, so that after calling swap(x,y) the values of x and y will be swapped. You could create such a method for mutable classes by swapping their contents¹, but this would not change their object identity and you could not define a general method for this.

You can however write a method that swaps two items in an array or list if that's what you want.

¹ For example you could create a swap method that takes two lists and after executing the method, list x will have the previous contents of list y and list y will have the previous contents of list x.

The interrupt process is hardware and OS dependent. So you will have very different behavior depending on where you run your python script. For example, on Windows machines we have Ctrl+C (SIGINT) and Ctrl+Break (SIGBREAK).

So while SIGINT is present on all systems and can be handled and caught, the SIGBREAK signal is Windows specific (and can be disabled in CONFIG.SYS) and is really handled by the BIOS as an interrupt vector INT 1Bh, which is why this key is much more powerful than any other. So if you're using some *nix flavored OS, you will get different results depending on the implementation, since that signal is not present there, but others are. In Linux you can check what signals are available to you by:

$ kill -l
 1) SIGHUP       2) SIGINT       3) SIGQUIT      4) SIGILL       5) SIGTRAP
 6) SIGABRT      7) SIGEMT       8) SIGFPE       9) SIGKILL     10) SIGBUS
11) SIGSEGV     12) SIGSYS      13) SIGPIPE     14) SIGALRM     15) SIGTERM
16) SIGURG      17) SIGSTOP     18) SIGTSTP     19) SIGCONT     20) SIGCHLD
21) SIGTTIN     22) SIGTTOU     23) SIGIO       24) SIGXCPU     25) SIGXFSZ
26) SIGVTALRM   27) SIGPROF     28) SIGWINCH    29) SIGPWR      30) SIGUSR1
31) SIGUSR2     32) SIGRTMAX

So if you want to catch the CTRL+BREAK signal on a linux system you'll have to check to what POSIX signal they have mapped that key. Popular mappings are:

CTRL+\     = SIGQUIT 
CTRL+D     = SIGQUIT
CTRL+C     = SIGINT
CTRL+Z     = SIGTSTOP 
CTRL+BREAK = SIGKILL or SIGTERM or SIGSTOP

In fact, many more functions are available under Linux, where the SysRq (System Request) key can take on a life of its own...

Use MimeTypeMap package, which provides a huge two-way mapping of file extensions to mime types and mime types to file extensions

using MimeTypes;

Getting the mime type to an extension

Console.WriteLine("txt -> " + MimeTypeMap.GetMimeType("txt"));  // "text/plain"

Getting the extension to a mime type

Console.WriteLine("audio/wav -> " + MimeTypeMap.GetExtension("audio/wav")); // ".wav"

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.

The first example doesn't work because you can't assign values to arrays - arrays work (sort of) like const pointers in this respect. What you can do though is copy a new value into the array:

strcpy(p.name, "Jane");

Char arrays are fine to use if you know the maximum size of the string in advance, e.g. in the first example you are 100% sure that the name will fit into 19 characters (not 20 because one character is always needed to store the terminating zero value).

Conversely, pointers are better if you don't know the possible maximum size of your string, and/or you want to optimize your memory usage, e.g. avoid reserving 512 characters for the name "John". However, with pointers you need to dynamically allocate the buffer they point to, and free it when not needed anymore, to avoid memory leaks.

Update: example of dynamically allocated buffers (using the struct definition in your 2nd example):

char* firstName = "Johnnie";
char* surname = "B. Goode";
person p;

p.name = malloc(strlen(firstName) + 1);
p.surname = malloc(strlen(surname) + 1);

p.age = 25;
strcpy(p.name, firstName);
strcpy(p.surname, surname);

printf("Name: %s; Age: %d\n",p.name,p.age);

free(p.surname);
free(p.name);

You can show all commits that you have locally but not upstream with

git log @{u}..

@{u} or @{upstream} means the upstream branch of the current branch (see git rev-parse --help or git help revisions for details).

Java actually has no modulo operator the way C does. % in Java is a remainder operator. On positive integers, it works exactly like modulo, but it works differently on negative integers and, unlike modulo, can work with floating point numbers as well. Still, it's rare to use % on anything but positive integers, so if you want to call it a modulo, then feel free!

For anyone who looks at this today after 2 years, Visual Studio 2019 (Community edition as well) shows the references

ID provides a unique indentifier for the element, in case you want to manipulate it in JavaScript. The class attribute can be used to treat a group of HTML elements the same, particularly in regards to fonts, colors and other style properties...

It's due to the missing of ojdbc6.jar in the maven repository. download it Click Here

Add the dependency in the pom.xml file

   <dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc6</artifactId>
        <version>11.2.0</version>
    </dependency>

Install/Add Oracle driver to the local maven repository using the following command in command prompt.

1. open command prompt
2. change directory to the apache-maven/bin folder Eg: cd C:\Users\Public\Documents\apache-maven-3.5.2\bin

3. type the command

   mvn install:install-file -Dfile={path/to/your/ojdbc.jar} -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

Eg: mvn install:install-file -Dfile=C://Users//Codemaker//Downloads//Compressed//ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

NB: use double back slash to seperate folders (//)

This is how I did it. You can try

    public class ABCService {
    @Resource(name="ABCDao")
    ABCDao abcDao;

    public int addNewABC(ABC abc) {
         ABC.setId(0);
         return abcDao.insertABC(abc);
    }
}

which git &> /dev/null || { echo >&2 "I require git but it's not installed.  Aborting."; exit 1; }
echo "Git is installed."

That will echo "Git is installed" if it is, otherwise, it'll echo an error message. You can use this for scripts that use git

It's also customizable, so you can change "which git" to "which java" or something, and change the error message.

If it helps anyone, and this may be laughable, but not obvious to me, was the application pool was not started. I just presumed on starting the website or creating the application pool, it would start. In fact, I didn't even know you had to start the application pool...

Self validated model

Your model should implement an interface IValidatableObject. Put your validation code in Validate method:

public class MyModel : IValidatableObject
{
    public string Title { get; set; }
    public string Description { get; set; }

    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        if (Title == null)
            yield return new ValidationResult("*", new [] { nameof(Title) });

        if (Description == null)
            yield return new ValidationResult("*", new [] { nameof(Description) });
    }
}

Please notice: this is a server-side validation. It doesn't work on client-side. You validation will be performed only after form submission.

.vscode/launch.json file is only used by Visual Studio as well as /Properties/launchSettings.json file. Don't use these files in production.

The launchSettings.json file:

1. Is only used on the local development machine.
2. Is not deployed.

3. contains profile settings.

   • Environment values set in launchSettings.json override values set in the system environment

To use a file 'appSettings.QA.json' for example. You can use 'ASPNETCORE_ENVIRONMENT'. Follow the steps below.

1. Add a new Environment Variable on the host machine and call it 'ASPNETCORE_ENVIRONMENT'. Set its value to 'QA'.
2. Create a file 'appSettings.QA.json' in your project. Add your configuration here.
3. Deploy to the machine in step 1. Confirm 'appSettings.QA.json' is deployed.
4. Load your website. Expect appSettings.QA.json to be used in here.

I'm going to give you an example of how I read REST headers for my controllers. My controllers only accept application/json as a request type if I have data that needs to be read. I suspect that your problem is that you have an application/octet-stream that Spring doesn't know how to handle.

Normally my controllers look like this:

@Controller
public class FooController {
    @Autowired
    private DataService dataService;

    @RequestMapping(value="/foo/", method = RequestMethod.GET)
    @ResponseBody
    public ResponseEntity<Data> getData(@RequestHeader String dataId){
        return ResponseEntity.newInstance(dataService.getData(dataId);
    }

Now there is a lot of code doing stuff in the background here so I will break it down for you.

ResponseEntity is a custom object that every controller returns. It contains a static factory allowing the creation of new instances. My Data Service is a standard service class.

The magic happens behind the scenes, because you are working with JSON, you need to tell Spring to use Jackson to map HttpRequest objects so that it knows what you are dealing with.

You do this by specifying this inside your <mvc:annotation-driven> block of your config

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper" ref="objectMapper" />
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

ObjectMapper is simply an extension of com.fasterxml.jackson.databind.ObjectMapper and is what Jackson uses to actually map your request from JSON into an object.

I suspect you are getting your exception because you haven't specified a mapper that can read an Octet-Stream into an object, or something that Spring can handle. If you are trying to do a file upload, that is something else entirely.

So my request that gets sent to my controller looks something like this simply has an extra header called dataId.

If you wanted to change that to a request parameter and use @RequestParam String dataId to read the ID out of the request your request would look similar to this:

contactId : {"fooId"} 

This request parameter can be as complex as you like. You can serialize an entire object into JSON, send it as a request parameter and Spring will serialize it (using Jackson) back into a Java Object ready for you to use.

Example In Controller:

@RequestMapping(value = "/penguin Details/", method = RequestMethod.GET)
@ResponseBody
public DataProcessingResponseDTO<Pengin> getPenguinDetailsFromList(
        @RequestParam DataProcessingRequestDTO jsonPenguinRequestDTO)

Request Sent:

jsonPengiunRequestDTO: {

which gets automatically serialized back into an DataProcessingRequestDTO object before being given to the controller ready for me to use.

As you can see, this is quite powerful allowing you to serialize your data from JSON to an object without having to write a single line of code. You can do this for @RequestParam and @RequestBody which allows you to access JSON inside your parameters or request body respectively.

Now that you have a concrete example to go off, you shouldn't have any problems once you change your request type to application/json.

Echo inside an HTML element with class and style the element:

echo "<span class='name'>" . $ip['cityName'] . "</span>";

To add to what Evan said: C does not have a built-in operator for exponentiation, because it is not a primitive operation for most CPUs. Thus, it's implemented as a library function.

Also, for computing the function e^x, you can use the exp(double), expf(float), and expl(long double) functions.

Note that you do not want to use the ^ operator, which is the bitwise exclusive OR operator.

In web.config under

<system.webServer>

replace (or add) the line

<httpErrors errorMode="Detailed"></httpErrors>

with

<httpErrors existingResponse="PassThrough" errorMode="Detailed"></httpErrors>

This is because by default IIS7 intercepts HTTP status codes such as 4xx and 5xx generated by applications further up the pipeline.

Next, enable "Send Errors to Browser" under the "ASP" section, and under "Error Pages / Edit Feature Settings", select "Detailed errors".

Also, give Write permissions on the website folder to the IIS_IUSRS builtin group.

When wrapping a pointer in a unique_ptr you cannot have multiple copies of unique_ptr. The shared_ptr holds a reference counter which count the number of copies of the stored pointer. Each time a shared_ptr is copied, this counter is incremented. Each time a shared_ptr is destructed, this counter is decremented. When this counter reaches 0, then the stored object is destroyed.

There are several versions of the clearfix, with Nicolas Gallagher and Thierry Koblentz as key authors.

If you want support for older browsers, it's best to use this clearfix :

.clearfix:before, .clearfix:after {
    content: "";
    display: table;
}

.clearfix:after {
    clear: both;
}

.clearfix {
    *zoom: 1;
}

In SCSS, you should use the following technique :

%clearfix {
  &:before, &:after {
    content:" ";
    display:table;
  }

  &:after {
    clear:both;
  }

  & {
    *zoom:1;
  }
}

#clearfixedelement {
    @extend %clearfix;
}

If you don't care about support for older browsers, there's a shorter version :

.clearfix:after {
    content:"";
    display:table;
    clear:both;
}

You can also check the .Any() method:

if (!YourResult.Any())

Just a note that .Any will still retrieve the records from the database; doing a .FirstOrDefault()/.Where() will be just as much overhead but you would then be able to catch the object(s) returned from the query

I faced the same with my parent test setUp class which has annotation @RunWith(SpringRunner.class) and was being extended by other testClasses. As there was not test in the setUpclass , and Junit was trying to find one due to annotation @RunWith(SpringRunner.class) ,it didn't find one and threw exception

No runnable methods exception in running JUnits

I made my parent class as abstract and it worked like a charm .

I took help from here https://stackoverflow.com/a/10699141/8029525 . Thanks for help @froh42.

Add these dependencies for run mockito successfully :

testImplementation 'org.mockito:mockito-core:2.24.5'
testImplementation "org.mockito:mockito-inline:2.24.5"

The triple quotes answer is great for ASCII art, but for those wondering - what if my multiple lines are a tuple, list, or other iterable that returns strings (perhaps a list comprehension?), then how about:

print("\n".join(<*iterable*>))

For example:

print("\n".join(["{}={}".format(k, v) for k, v in os.environ.items() if 'PATH' in k]))

Just wondering why you are using 2 directives?

It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.

Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).

It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.

Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

I'm not sure that I understood your problem, but I think you can divide loop. On the part of the function and the part without it and save the two loops.

First, you need to create selfsigned.key and selfsigned.crt files. Go to Create a Self-Signed SSL Certificate Or do following steps.

Go to the terminal and run the following command.

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./selfsigned.key -out selfsigned.crt

• After that put the following information
• Country Name (2 letter code) [AU]: US
• State or Province Name (full name) [Some-State]: NY
• Locality Name (eg, city) []:NY
• Organization Name (eg, company) [Internet Widgits Pty Ltd]: xyz (Your - Organization)
• Organizational Unit Name (eg, section) []: xyz (Your Unit Name)
• Common Name (e.g. server FQDN or YOUR name) []: www.xyz.com (Your URL)
• Email Address []: Your email

After creation adds key & cert file in your code, and pass the options to the server.

const express = require('express');
const https = require('https');
const fs = require('fs');
const port = 3000;

var key = fs.readFileSync(__dirname + '/../certs/selfsigned.key');
var cert = fs.readFileSync(__dirname + '/../certs/selfsigned.crt');
var options = {
  key: key,
  cert: cert
};

app = express()
app.get('/', (req, res) => {
   res.send('Now using https..');
});

var server = https.createServer(options, app);

server.listen(port, () => {
  console.log("server starting on port : " + port)
});

• Finally run your application using https.

Use this:

mocha server-test

Or if you have subdirectories use this:

mocha "server-test/**/*.js"

Note the use of double quotes. If you omit them you may not be able to run tests in subdirectories.

    var css_link = $("<link>", {
        rel: "stylesheet",
        type: "text/css",
        href: "yourcustomaddress/bundles/andreistatistics/css/like.css"
    });
    css_link.appendTo('head');

I would put each element that you want inline inside a separate col-md-* div within your row. Or force your elements to display inline. The form-control class displays block because that's the way bootstrap thinks it should be done.

KOTLIN

There is also the possibility to use sufficientlysecure.htmltextview.HtmlTextView

Use like below in gradle files:

Project gradle file:

repositories {
    jcenter()
}

App gradle file:

dependencies {
implementation 'org.sufficientlysecure:html-textview:3.9'
}

Inside xml file replace your textView with:

<org.sufficientlysecure.htmltextview.HtmlTextView
      android:id="@+id/allNewsBlockTextView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_margin="2dp"
      android:textColor="#000"
      android:textSize="18sp"
      app:htmlToString="@{detailsViewModel.selectedText}" />

Last line above is if you use Binding adapters where the code will be like:

@BindingAdapter("htmlToString")
fun bindTextViewHtml(textView: HtmlTextView, htmlValue: String) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    textView.setHtml(
        htmlValue,
        HtmlHttpImageGetter(textView, "n", true)
    );
    } else {
        textView.setHtml(
        htmlValue,
        HtmlHttpImageGetter(textView, "n", true)
        );
    }
}

More info from github page and a big thank you to the authors!!!!!

I have too low reputation to add comment to @bernie response, with response to @user1506145. I have run in to same issue.

The answer to it is a interval parameter which fixes things up

import matplotlib.pyplot as plt
import matplotlib.dates as mdates
import numpy as np
import datetime as dt

np.random.seed(1)

N = 100
y = np.random.rand(N)

now = dt.datetime.now()
then = now + dt.timedelta(days=100)
days = mdates.drange(now,then,dt.timedelta(days=1))

plt.gca().xaxis.set_major_formatter(mdates.DateFormatter('%Y-%m-%d'))
plt.gca().xaxis.set_major_locator(mdates.DayLocator(interval=5))
plt.plot(days,y)
plt.gcf().autofmt_xdate()
plt.show()

You may use bellow like in angular 9

 <select [(ngModel)]="itemId"  formControlName="itemId" class="form-control" >
          <option [ngValue]="" disabled>Choose Gender</option>             
          <option *ngFor="let item of items"  [ngValue]="item .id" [selected]="item .id == this.id"  >
             {{item.name}}
          </option>
   </select>

You can't. Full stop.

switch is only for integral types, if you want to branch depending on a string you need to use if/else.

In HTML,

<button disabled/>
<buttton disabled="true">
<buttton disabled="false">
<buttton disabled="21">

All of them boils down to disabled="true" that is because it returns true for a non-empty string. Hence, in order to return false, pass a empty string in a conditional statement like this.input.value?"true":"".

render() {
    return (
        <div className="add-item">
            <input type="text" className="add-item__input" ref={(input) => this.input = input} placeholder={this.props.placeholder} />
            <button disabled={this.input.value?"true":""} className="add-item__button" onClick={this.add.bind(this)}>Add</button>
        </div>
    );
}

Here is my combined solution for various PHP versions.

In my company we are working with different servers with various PHP versions, so I had to find solution working for all.

$phpVersion = substr(phpversion(), 0, 3)*1;

if($phpVersion >= 5.4) {
  $encodedValue = json_encode($value, JSON_UNESCAPED_UNICODE);
} else {
  $encodedValue = preg_replace('/\\\\u([a-f0-9]{4})/e', "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode($value));
}

Credits should go to Marco Gasi & abu. The solution for PHP >= 5.4 is provided in the json_encode docs.

I recommend using any of these two commands.

git branch | grep -e "^*" | cut -d' ' -f 2

OR

git status | sed -n 1p | cut -d' ' -f 3

OR (more verbose)

git status -uno -bs| cut -d'#' -f 3 | cut -d . -f 1| sed -e 's/^[ \t]//1'| sed -n 1p
